Congruence between voters and parties: The role of party-level issue salience

The level of congruence between parties and their voters can vary greatly from one policy issue to another, which raises questions regarding the effectiveness of political representation. We seek to explain variation in party–voter congruence across issues and parties. We focus on the hypotheses that (1) average proximity between the positions of voters and the party they vote for will be highest on the issues that the party emphasises in the election campaign and that (2) this relationship will be stronger for niche parties. We test these hypotheses using data on the policy preferences of voters, party positions, party attention profiles and salience on concrete policy issues in four countries: The Netherlands, Ireland, Germany and Sweden. Overall, we find that voter–party proximity tends to be higher on issues that the party emphasises. As these are the issues where parties typically have the greatest policy impact, this implies that the quality of representation is highest where it matters most. There is some limited evidence that the positive relationship between issue salience and proximity is stronger for niche parties. In sum, the quality of policy representation varies strongly with party-level issue salience and to a lesser extent with the type of political party.     

The effects of populism as a social identity frame on persuasion and mobilisation: Evidence from a 15-country experiment

This article investigates the impact of populist messages on issue agreement and readiness for action in 15 countries (N = 7,286). Specifically, populist communicators rely on persuasive strategies by which social group cues become more salient and affect people's judgment of and political engagement with political issues. This strategy is called ‘populist identity framing’ because the ordinary people as the in-group is portrayed as being threatened by various out-groups. By blaming political elites for societal or economic problems harming ordinary people, populist communicators engage in anti-elitist identity framing. Another strategy is to blame immigrants for social problems – that is, exclusionist identity framing. Finally, right-wing political actors combine both cues and depict an even more threatening situation of the ordinary people as the in-group. Based on social identity theory, an experimental study in 15 European countries shows that most notably the anti-elitist identity frame has the potential to persuade voters. Additionally, relative deprivation makes recipients more susceptible to the mobilising impact of the populist identity frames.
